Paradise fish often are too aggressive for a community. You can try but be prepared to remove it if trouble starts. If you want German Blue Rams they need to be added about 6 months after the tank has been set up. They do poorly in new tanks and are very sensitive to nitrates so large weekly WC
's are a must. Bolivian Rams can be added sooner and are a much hardier fish. And remember you can go get a ton of fish and add them all at once. You have to spread it out over a few weeks depending on how many you want to add. 2 Angelfish, a Honey or Pearl Gourami, a couple schools of tetras like Cardinals, Rummy Nose, Diamond, or Lemons would work well. Rasbora's are an option also. You could do Cory Cats or Yo-Yo Loaches for bottom fish (I keep both in my 220g). Check out whiptail cats, they are a sucker catfish and very unique. If you want larger schooling fish then look into Rainbowfish as with them you have alot of color. You can use the small Threadfin rainbowfish as a top schooling fish with either option.
My suggestion would be go to your LFS
, see what they have that you like and write the names down, come home and reseach each fish to see how big they get, are they good community fish, how big a tank do they need, etc. Then make a list of what you think you want for your tank and slowly start collecting a few at a time.
